Specification of Letters iPatent.

Patented Sept. 29, 1908.

To all-whom it may concern:

Be it known'that I, CHARLES SMITH, States, and resident of the borough of Brook yn, cit of New York, in the county ofKings'an Im rovements inlype-WIiting Machines,- of Which the following is a specification.

My invention relates to ribbon mechanism for typewriting machines and more particu larlyto mechanism in which a ribbon is or may be automatically moved into the path of tion.

One object of my invention is to provide, in a construction of the character specified, sim 1e and efficient means for regulating the anism so that any desired field of the ribbon" may be presented for cooperation with theprintirig instrumentalities, this feature of my invention contemplating the use of a ribbon having fields of different characteristics, although it is also useful'in connection with a one-color ribbon, i

Anotherobject of my invention is to'provide means for renderin the mechanism inilbon (polychrome or machine may he-readily-employed for the preparationof mimeograph s eet-s when'de- To the above and other ends which will hereinafter'appear, my invention consists of the features of construction,-. arrangements of parts and combinations of devices described in the following specification and set forth in the accompanying claims.

characters indicate elevation of the upper In the drawlngs, wherein like reference the various views, Fi ure 1 is a vertical central sectionaLview ta..en fore and aft of. the machine, of a sufficient number of parts of a typewriting machine to show my invention in it'sa'pphcation thereto. Pig. 2 is a front ortion' ofsaid machine. Pig. 3 is a detai plan view of a portion of the ribbon" vibrating mechanismwith parts broken away and parts shown in section. Fig. 4 is an enlarged detail vertical Sectional viewof a portion of the ribbon vibrating mechanism, parts of the construction being shown in sideelevation'.

I have shown my invention ap lied to a Monarch machine in whichit may hereadily employed without changing any of the struc- State of New York, have invented certain new and useful corresponding parts intural features of such machines, though it sh oul d'be understood that the invention may be applied to other styles of machines.

Certain of the features shown in the present case are claimed broadly in my compan; ion a plication Serial N 0. 337,738 filed of even ate herewith, the present case being re- .stricted 'to features either not contained or not claimed in said compamon application.

The. framing of the machine comprises a base 1, corner posts 2 and-a top plate 3. Key levers 4 are fulcrumed against a fulcrum plate 5 in the base of the machineand are each provided with a restoring spring 6 and a key 7. Each key lever has pivoted thereto at- 8 a sub-lever 9 connected at its up er end as at 10 to a forwardly extending lin '11 pivoted at 12 to a type bar 13. The lower end of each sub-lever is slotted at 14 for cooperation with a fulcrum rod "15 which extends bcneaththe key levers and is socured at its ends in the base of the machine. The type-bars 13 are segmentally arranged and are carried by hangers 16 secured by screws 17 to a type bar segment 18. The type bars are supported at their forward ends on a pad 19 mounted on a segmental strip 20 supported by rods 21 which project forwardly from the type bar segment. The type bars strike upwardly and rearwardly against the front face of the platen 22, diagrammatically shown in Figs. 1 and 2. The

platen 22 is carried by a carriage which moves from side to side of the machine over the top plate 3 in the usual manner, said carriage being connected to one end of a band23 which has its other end secured to a spring drum 24 toeffect a step-by-step let tcr feed movement of the carriage from right to left in the usual manner when the escapement mechanism (not shown) is actuated. The sprin I drum actuates a beveled pinion 25 througi a pawl and ratchet connection (not shown) which turns said pinion when the carriage is moving in letter space direction, but not in the other direction. Said pinion 25 meshes with a pinion 20 having a 1ub 27 with a slot 28 therein for the rewotion of a pm 29 projecting from a shaft iii. The shaft 30 is mounted in bracket arms 31,

32 depending from the top plate and is adapted to receive a longitudinal as well as a rotary movement in its bearings. The brackc arm 31 bears against the end of the hub 27 to prevent a movement of the pinion 26 with its shaft 7 during the longitudinal movement thereof in one direction and the pinions and 26 codperate to prevent movement of the pinion 26 with the shaft in the opposite direction onto the left. The construction is such, therefore, that the shaft 30 will rotate with the pinion 26 but independent longitudinal movement of the shaft is aiiorded.

. The'left-hand end of the shaft is provided with a beveled inion 33 for 006 eration with a beveled pinion 34. The pimon 34 is mounted on the rear end of a shaft 35 which turns in bearings 36, 37 which are in the nature of dependin bracket arms on the top plate of the mac ine. The forward'end of the shaft 35 carries a beveled pinion 38 which meshes with a gear 39 connected with or right-hand end of t e shaft 30 is provided the left-handribbon s 00140. The opposite field a may be of one color and the field b, of

another coloror tllie field a may be record ribbon and the fie d 1) copying ribbon. In the )assage of the ribbon from one s )ool to anot er asshown in Fig. 2 it passes through guide openings in a ribbon vibrator 48 which 1s of the usual construction and is guided in its vertical movement by a fixed guide 49.

The ribbon vibrator has a depending stem 50 pivoted at 51 to the forwardly extending arm of a ribbon vibrator actuating lever 52 pivoted 211 53 to a depending "bracket 54 on the top )late of the machine. The rear end of tl1e ever 52'is pivotally connected at 55 to an upright link 56. 45

The lower end of this link is pivoted at 57 to a crank arm or device 58. *rom an mspection of Figs. 3 and 41t will be seen that this crank arm 58 is formed as a projection on an inner tubular-like member 59 and projects through a slot 60 in a surrounding tubular universal bar 61 in which the member 59 is received and adapted to turn, the tube 59 receiving a bearing in the universal bar 61. One side wall of the slot 60 is provided with three notches or depressions 62, 63 and 64 in which a spring-pressed pawl or detent 65 is adapted to engage. This pawl is preferably,struck up from spring metal and has an angular base 66 which is riveted to'the inner tube 59 as indicated at -67 in Fig. 4. The tension of the pawl or detent 65 is exerted to maintain it in either of the depressions 62, 63 or 64. The dctent 65 riveted to the lower portion of the tubular member 59as shown in Figs. 3 and 4 and cease? projects through an enlarged opening 68 in 65 the upper part of the tubular member 59. The universal bar 61 is provided with a depending car 69 at the left-hand end thereof and said ear is apertured for the race tion of a screw 70 that is received in a t readed opening in the left-hand side arm 71 of the universal bar frame-made up of the side arms 71, a cross bar 72 from which a rearwardly extending arm 73 extends and a rock shaft 74 mounted at its ends on cone ivot screws 75 which are received in three ed openin s in the base 1 of the machine at each si e thereof. The right-hand end of the inner tube .59 is internally threaded for cooperation with a headed screw 76 which screw in turn is internally threaded to receive a threaded stem 77 of a finger piece 78. The projecting part 79 of the stem of said finger iece extends through a slot 80 in the rightand side of the base 1 of the machine in or der that the finger piece will not interfere with the up and down movement of the universal bar, and so that the tubular member 59 may be turned in its bearing by the finger piece 78 from outside of the machine. The stem 79 of the finger iece, has a cylindrical bearing portion 81 w \ich is received in a bearing opening in the right-hand side arm 71 of the universal bar frame. The lefthand end of the rotativc adjusting member 59 is internally threaded to receive a stem 82 of a headed screw which, like the screw 76, has aninternally threaded central opening for coeperation with a threaded stem 83 of a headed shouldered screw 84, the cylindrical portion 85 thereof being received in a bearing opening in the left-hand side arm 71 of the universal bar frame, the universal bar 61 being secured by its car 69 and screw 70 to the universal bar frame and maintained fixed. while the linger piece 78 maybe employed to turn the tubular member 59 to adjust the crank arm 58 on said member relatively to the universal bar. The effect of this adjustment is to change the normal osition of the link 56, vibrator actuating ever 52 and the ribbon vibrator 48 so as to bring either field a or b of the ribbon into use or to lower the ribbon vibrator to a position where the depression of the finger key 7 will be ineffective to bring the ribbon to the printing point even though the universal bar is depressed the usual distance. Thus, by eil'ecting a rota-tive adjustment of the crank arm 58 through the finger piece 78 to a position where the detent 65 is received in the notch 63, the actuating lever 52 of the vibrator is positioned normally in the full line position shown in Fig. 4 and will be moved at each printing operation to the dotted line position 0 to bring the uppermost or black held (I of the ribbon to the printing point.

-An adjustment of the crank arm' 58' through the finger 78 t6 a position where the spring detent 65 engages'the,notch 62, changes the normal-position of the vibrator actuating lever to the position 'indi-r cated at d in Fig. 4, the lever being vibrated at each printing 'operation to the position represented at e t br-ing' the lowermostor:

red field b of the ribbon to the 'printing posi 'tion. When therotative member, 59 is adjusted through the finger piece 78 toflseat the x spring detent 65 inthe notch 64, thenthe forward; end of the ribbon vibratinglever. 52 will be depressed its'normal position to the lowermost pointwhich it is capableof at taining and which-is represented at f in Fig.

4. Each printing 0 eration will 1 effect .a

movementof the vi rator actuating lever,

from thei'position "shown at to that indicated at (1 when the parts are in the last mentioned adjusted position; "The extent of this a movement is insuflicientto' bring the ribbon 'to the printing point so that while the ribbon vibrator is actuated inthe usual "manner it is, nevertheless, inoperative to bring the ribbonto the printing point. and the parts; are arranged at this time for the preparation of'mimeograph sheets; The rearwardly-extending arm 7 3 which projects from the umversal bar frame is pivotedat 85 tofan u wardly extending link 86 connected int e usual manner to the escapement mechanism so that each depression of a'keylever not only efiects an'operation of the. ribbon vi brat'orj in the manner described but also eflectsan operation of-the escapement 'mech-.

anism to afiord a ste by-s tep fced of the carriage from right to eft.

Itwill be seen thatby my present invention I provide constantly maintained connections between the universal bar and the ribbon vibrator and that there is no lost motion efie'cted between any of the parts- Whetherthefield a or b of the ribbon is in use or the ribbon vibrating mechanism is renderedinefiective to move theribbon to r the printing "point; that there is no connection or disconnection eifected between the parts; that consequently the "touch on the ger keys is uniform at all times irrespective of the adjustment of the member 59;-that V the mechanism is simple in construction and reliable in operation;v and that'there is little liabilityof the mechanism becoming de-v.

ranged or broken The universal bar me and the parts eerried thereby may be restored to normal. ositio'n after each actuationby the usual og rocker restoring spring (not shown) or a separate restoring spring-i rusty be employed for this'purp arious c ose. anges may be mm c without departing from my invention. e
